AI SaaS companies whose per-user flat monthly subscriptions are being eroded by heavy LLM/GPU inference power users frequently search to hire a freelance AI credit wallet, token metering & hybrid subscription billing programmer. I am Aldian Fazrihady, a Senior Freelance Full Stack Developer and AI Application Engineer.
Core AI Token Metering & Credit Wallet Capabilities
- Real-Time Atomic Credit Deduction: Tracking prompt/completion tokens, audio minutes, and image generation credits per request using atomic Redis + PostgreSQL ledger deductions so users cannot exceed their prepaid balance.
- Hybrid Seat + Usage Overages + Auto-Top-Up: Combining monthly base tier allowances with automatic Stripe off-session credit top-up charges when a workspace balance drops below a configurable threshold.
- Transparent Customer Usage Dashboards: Building interactive React charts showing token consumption by model, team member, and API key.
Frequently Asked Questions
How do you handle credit reservation before a streaming LLM call finishes?
I place a pre-authorization credit hold based on `max_tokens` before initiating the LLM stream, and settle the exact actual token cost from the final usage chunk upon stream completion.
